GDAL is a C++ translator library for more than 200 raster and vector geospatial data formats. It offers an API for a variety of languages such as C, C++, Python, Perl, C# and Java.
vdPConsulting has investigated whether and how this GDAL/OGR functionality can be implemented in a C# plugin in AutoCAD.
As Proof of Concept II, the download of the BGT and BRK/DKK from the PDOK website has been implemented. Based on a project polygon, a location filter is created and sent to PDOK as a spatial query. The result is downloaded (as a ZIP-file) and extracted into the project folder and then imported into AutoCAD.
